A butterfly count is an event that is organized for the purpose of identifying and counting butterflies in a specific geographical area. Butterfly counts occur regularly in North America and Europe. thumb The counts are conducted by interested, mostly non-professional, residents of the area who maintain an interest in determining the numbers and species of butterflies in their locale. A butterfly count usually occurs at a specific time during the year and is sometimes coordinated to occur with other counts which may include a park, county, entire state or country. The results of the counts are usually shared with other interested parties including professional lepidopterists and researchers. The data gathered during a count can indicate population changes and health within a species. == Sponsors == Professional, universities, clubs, elementary and secondary schools, other educational providers, nature preserves, parks and amateur organizations can organize a count. The participants often receive training to help them identify the butterfly species. The North American Butterfly Association has organized over 400 counts in 2014.〔 (【引用サイトリンク】 url = http://www.naba.org/counts/us_mx_map.html ) 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Butterfly count」の詳細全文を読む スポンサード リンク
